MySQL ORDER BY Multiple Columns

In MySQL, multiple sorting conditions can be achieved using ORDER BY clause and multiple column names. For example, the following syntax can be used to sort multiple columns:

SELECT * FROM table_name
ORDER BY column1, column2, column3;

The statement above will be sorted in ascending order based on the values in column1. If the values in column1 are the same, then it will be sorted based on the values in column2, and so on. If you need to sort some columns in ascending order and others in descending order, you can add the DESC keyword after the column name.

SELECT * FROM table_name
ORDER BY column1 ASC, column2 DESC;

The statement will be ordered in ascending order according to the values in column1, and if the values in column1 are the same, they will be sorted in descending order based on the values in column2.

In practical use, multiple column names and sorting methods can be flexibly combined based on specific needs to achieve multi-condition sorting.
